Answer 1

$\huge{\mathcal{\green{\underline{Answer}}}}$

$(2x + 3y) {}^{2} = 4x {}^{2} + 9y {}^{2} + 6xy$

Answer 2

Step-by-step explanation:

$(2x + 3y) {}^{2} \\ \\ (2x) {}^{2} + 2 \times 2x \times 3y + (3y) {}^{2} \\ \bold{using \: the \: identity \: of \: - } \\ \bold{ (a + b) {}^{2} = a {}^{2} + 2ab + b} {}^{2} \\ \\ 4x {}^{2} + 12xy + 9y {}^{2}$
